Lentopolttoaineeksi

Lentopolttoaineeksi, often referred to as aviation fuel or avgas, is a specialized petroleum-based fuel used in piston-engine aircraft. Unlike jet fuel, which powers turbines, lentopolttoaineeksi is designed for the specific combustion characteristics of internal combustion engines found in many general aviation aircraft. Its formulation includes a high octane rating to prevent engine knocking or detonation, particularly under the demanding conditions of flight. The octane number is critical for maintaining engine performance and preventing damage.

The production of lentopolttoaineeksi involves refining crude oil and adding specific additives to enhance its properties. These additives can include anti-knock agents, anti-icing compounds, and corrosion inhibitors, all of which contribute to the safe and efficient operation of aircraft engines. The color of lentopolttoaineeksi can vary depending on the grade, with common colors including blue for Avgas 100LL (low lead) and green for Avgas 100.

The use of lead, specifically tetraethyllead, as an octane enhancer has been a characteristic of lentopolttoaineeksi for decades. However, environmental and health concerns associated with lead emissions have led to a global effort to phase out leaded avgas. Research and development are ongoing to produce viable unleaded alternatives that meet the stringent performance requirements of piston aircraft engines. The transition to unleaded avgas is a significant undertaking for the aviation industry, requiring new fuel formulations and potentially modifications to aircraft engines.
